What is threading in C++ and how can I use it?

Threading in C++ allows multiple threads to run concurrently, improving performance for tasks that can be parallelized.

Can you give me an example of how to create a thread in C++?

Sure! You can use the <thread> library. Here's a simple example:

#include <iostream>
#include <thread>

void hello() {
    std::cout << "Hello from thread!" << std::endl;
}

int main() {
    std::thread t(hello);
    t.join(); // Wait for the thread to finish
    return 0;
}
}```

What are some common issues I might face with threading?

Common issues include race conditions, deadlocks, and resource contention. Proper synchronization is key to avoid these.

How can I synchronize threads in C++?

You can use mutexes from the <mutex> library to synchronize access to shared resources, preventing race conditions.
